Homes that are professionally cleaned before listing sell 15% faster and for an average of $3,000 more than comparable homes that aren't. That's a significant return on a $150–$300 cleaning investment.
Start with the kitchen. Clean inside every cabinet and drawer, degrease the oven and range hood, descale the dishwasher, and wipe down every surface including the tops of cabinets. Buyers open everything.
In bathrooms, re-caulk any discolored grout lines, deep-clean tile and grout with a brush, replace toilet seats if worn, and polish all fixtures until they shine. Bathrooms are make-or-break rooms for buyers.
For living areas, clean baseboards, door frames, and light switches — the things people touch every day but rarely clean. Wash windows inside and out. Steam-clean carpets or have hardwood floors professionally polished.
Don't forget the garage, basement, and attic. Buyers explore everything. A clean, organized garage signals a well-maintained home. Sweep, organize, and remove any oil stains from the floor.
Finally, address odors. Pet odors, cooking smells, and mustiness are deal-breakers. Air out the home for 24 hours before showings, use enzyme cleaners on any pet areas, and avoid heavy air fresheners which buyers find suspicious.
